   Several people immediately obeyed the order and retreated obediently.

Liu Jingyun couldn\'t hold down the bleeding part of the young man with the towel, and the blood continued to flow out and down. Knowing that her strength could not handle it, she made a judgment and said to the second junior sister, "Go and do heart compressions for Yingying and ask her to come over. !"

   turned around and ran, He Xiangyu rolled up her sleeves and came to the side of the little sister, pushed the little sister away, rushed up to press, and called the little sister: "You go to the big sister, I\'ll come here!"

   "Second Senior Sister, you have to keep pressing her, she has a sudden cardiac arrest, there is a chance—" Xie Wanying said to Senior Sister.

   "I know, if you don\'t stop me, I won\'t stop!" He Xiangyu plucked up her strength and planned to press it desperately, pressing it on the old man\'s chest hundreds of times a minute.

   This patient was handed over to the second senior sister first. Xie Wanying ran back and came to the senior sister and asked, "What\'s the situation?"

   "The bleeding can\'t be stopped!" Liu Jingyun pressed the patient\'s bleeding site so hard that her hands trembled, and her voice trembled.

   "Move away a little, let me see where the bleeding is." Xie Wanying said.

  Liu Jingyun was not very confident. The moment she slowly removed her hand and the towel, the blood was bubbling from the wound, so she couldn\'t help but cover it with the towel.

  People around you cover their faces and cover their eyes, and they don’t dare to look at them: too scary!

   At this time, only the surgeon would definitely dare to see it.

   asked the senior sister to move her hand away, Xie Wanying looked at the wound carefully and in detail, she must first identify the condition of the wound. A violent blow to the head may be called a traumatic brain injury or traumatic brain injury or traumatic brain injury. Craniocerebral injury is divided into scalp injury, skull injury or brain injury in the skull, and now this patient is one or both of the injuries need to be initially identified.

   The patient\'s pupillary reflexes are normal, but no abnormality is found. It can be preliminarily determined that there is no intracranial brain injury. The human skull is hard, and it is not very terrifying damage, and it is impossible to cause skull damage. So, it\'s likely just scalp damage.

  Don\'t underestimate the scalp injury, because the human scalp is rich in blood vessels, and the amount of bleeding will suddenly be large, which will cause the patient to shock.

   The patient\'s blood pressure was lowered, and the patient\'s lips were slightly pale. It\'s okay to stop the bleeding immediately. It\'s just that hemostasis on the scalp is not the same as hemostasis on other parts of the skin.

  The scalp is divided into five layers. Scalp injury and bleeding are damaged in the subcutaneous tissue layer instead of the skin layer. The abundance of blood vessels in the human scalp refers to the numerous blood vessels that are cut off by fibers in the subcutaneous tissue layer. Scalp injury subcutaneous blood vessels cannot shrink on their own, so there is a lot of bleeding. If the pressure cannot stop the bleeding, in addition to sutures, it is necessary to inject drugs to constrict the blood vessels of the scalp to stop the bleeding.

   "Come on, there is a yarn block!" The store manager found the first aid kit and brought it over. After opening it, there was finally a yarn block.

  Xie Wanying asked Senior Sister to take a piece of gauze to cover the wound, and after her eyes determined the scope of the wound, she pressed her finger on the scalp around the wound to stop the bleeding, so as to block the blood flow.

  The surrounding group of people watched with bated breath, and finally it seemed that the blood had not been pouring out all the time.

   "Gauze blocks and bandages." Xie Wanying gave instructions.

The person next to    hurriedly handed her tools. Take the gauze block and continue to press the part where her fingers are pressed, and then use a bandage to fix it.
